Progress Calculation Sample for Pump Installation Work

If you are preparing a progress calculation sheet for a work, a weighting factor for each work step and each WBS component is used to calculate to give the weighted progress. For example, to calculate percent completion for a pump installation, the following typical work steps and weight factors are required.

Work step	Weight factor
Chipping & Padding	10%
Installation	40%
Levelling & Grouting	20%
First Alignment	20%
Final Alignment	10%

The percent complete for a pump installation can be obtained by the sum of the product of each weight factor and each work step progress.

Pump Installation Progress = Chipping & Padding (10%)* work progress + Installation (40%)*work progress+ Levelling & Grouting (20%)*work progress + First Alignment (20%)*work progress +Final Alignment (10%)* work progress

Pump installation progress would be 10% when chipping & padding activity is done 100%. Percent completion would be 50%, 70%, 90% and 100% respectively when each work step is done 100%. Generally, progress calculation method for other work is the same although weight factors are different. Read more about weight factor for mechanical equipment installation work.
